8. prevailed not--A and Coptic read, "He prevailed not." But B and C read as English Version.
      neither--A, B, and C read, "not even" (Greek, "oude"): a climax. Not only did they not prevail, but not even their place was found any more in heaven. There are four gradations in the ever deeper downfall of Satan: (1) He is deprived of his heavenly excellency, though having still access to heaven as man's accuser, up to Christ's first coming. As heaven was not fully yet opened to man (Joh 3:13), so it was not yet shut against Satan and his demons. The Old Testament dispensation could not overcome him. (2) From Christ, down to the millennium, he is judicially cast out of heaven as the accuser of the elect, and shortly before the millennium loses his power against Israel, and has sentence of expulsion fully executed on him and his by Michael. His rage on earth is consequently the greater, his power being concentrated on it, especially towards the end, when "he knoweth that he hath but a short time" (Re 12:12). (3) He is bound during the millennium (Re 20:1-3). (4) After having been loosed for a while, he is cast for ever into the lake of fire.
